x10 for Trijicon Accupoint if you can afford but there are MANY MANY "ar15" scopes in that general power range (1-4, 1.5-4.5, etc) and size, with wide field of view (though heavier than say, an Accupoint), which will work well.
My favorite all-purpose budgety scope is the Nikon Omega 1.65-5x36. Since they are apparently discontinued, snap them up while you can (check Natchez SS). I have 6 and wish I had more. You can use them on centerfires, rimfires, scout scope placement, handguns, ar15s, anything.
By the way, the now-discontinued Trijicon Accupoint 1.25-4x24mm 1" tube scope is a much better scope for most purposes than the newer, more expensive 1.0-4x24 30mm tube Accupoint. Sure the latter gains you 0.25 less magnif on the low end to get you to 1.0x (but who cares - 1.25 is just as good, unlike 1.5, IMO) - but you give up an incredible amount of eye relief. The old one had about 5" of ER on 1.25x. The new one sucks with less than 3" I think.
